Produced in cooperation with the American Geological InstituteWith teacher's guide SummaryEstablishes a parallel between the constant flux of the atmosphere and hydrosphere and the deformation and movement of the lithosphere. Examines evidence that underground rock can simultaneously break and flow under high pressure and temperature.

Shows how Dr Joseph Smagorinsky and his colleagues at the Environmental Science Services Administration experiment with mathematical equations and computers for predicting the weather. Morris Shamos, Roscoe Braham of the University of Chicago, Louis Battan of the Institute for Atmospheric Physics, and Jerome Spar of the U.S. Weather Bureau discuss rain, hail, and lightning. Research is aimed at modifying large-scale weather systems, such as cyclones. From the Science and engineering TV journal...

Describes and develops the two mechanisms known to be responsible for the growth of cloud droplets to the size of raindrops coalescence and glaciation, beginning with the condensation of water vapor on water soluble nuclei in the atmosphere to form cloud droplets. Uses current experimental techniques and natural and time - lapse photography to illustrate the results of these processes. Describes Franco's rise to supreme power in Spain by virtue of the force of his personality and of the... Topics: Fomation of Raindrops, Earth sciences, Natural sciences, Physical sciences, Science
